[Music] 3D is all about working with objects so let's learn how to select them luckily it's pretty simple all we need to do is left click to select an object I'll left click on the camera then left click on the cube and I can go back and forth selecting each object you'll notice that whichever object is selected is outlined in Orange in the 3D view as we select different objects you'll also see that it's highlighted differently over here on the top right this editor is called the outliner and it's a hierarchical view of the scene we can also select things here so we can select the cube with just a left click and also we can select the light or the camera as we select different objects the editor below jumps around a little bit that's because this editor is the properties editor and different objects have different properties now things get a little bit more interesting when we start selecting multiple objects we can do that in the 3D view simply by holding down shift while selecting an object so the camera is currently selected but if I hold down shift and select the cube then I can add it to the selection the shift hotkey actually toggles the selection not just adds to it so I can also hold down shift left click on the cube and remove it from the selection so go ahead and practice adding and removing different objects from the selection shift left click on the cube shift left click on the light and then let's shift left click on the cube again but you'll notice that that didn't deselect it the clue as to why can be found in two places first the color of the outline is a brighter orange while the rest of the objects are a darker orange also in the outliner you can see that the cube has a brighter highlight than the others the reason it's highlighted differently is that the cube is currently the active object blender uses the idea of an active object for a couple different things but the most important one for now is that it's the one that's being edited in the properties editor so we can see we have the cube object here but then if I were to hold down shift and then left click on the camera it becomes the active object it's highlighted a little bit brighter than the others and we also see it appear in the properties editor so shift clicking on objects actually does a couple things first if the object is selected but not the active object a shift click will make it the active object but if it's the active object already then a shift click will deselect it we can also select multiple objects in the outliner and we can do that more like a file browser so we can also hold down shift here but that'll actually select the range in between two selections so if I select the camera and then shift select the light it'll select everything in between in that list also similar to a file browser I can use the control key to select multiple things without selecting anything in between I can also deselect everything by left clicking an empty space that works in the outliner as well as in the 3D view just left click in empty space and everything is deselected to select everything all at the same time we can go to select and then all if we don't have any empty space in the 3D view to click to deselect everything we can also go to select and then none the hotkey for those two are a and alt a and those would be really good to get used to a to select all alt a to deselect all one thing that's important to notice is that even though nothing is selected right now we still have the cube in the properties editor the icon for it is also highlighted a little bit different over in the outliner that's another indication that it's the active objects we can also see an orange dot in the center of it in the 3D view which is its origin something that we'll talk about much more in a later video but for now those are all signs that this is still the active object even though it's not selected in blender there always has to be one active object so you can't have no active objects and you can't have two or more active objects there's always going to be exactly one it's usually just the last selected one there are a whole lot more select operations that you can do in the select menu I don't have time to go over all of these now but it's worth exploring them in case you're curious now another way to select is to use the active tool you might have noticed the toolbar over here in the top left of the 3D View and here's where we can switch between our different active tools by default we're using the Box select tool and that just means that we can left click and drag anywhere in the 3D view in order to do a box select notice that a box select doesn't change the active object but whatever is inside the Box gets selected and anything that's outside the box gets deselected if we want we can change this Behavior up in the tool properties that's this little Notch underneath the main header if you don't see it then you can just go to view and turn on tool settings toggling that we'll turn it on and off if we want to switch this to the second icon then we can use the Box select to only add to the selection without deselecting anything else if we use a third icon then we can use it to only remove from the selection the fourth icon is going to invert the selection and the last one is going to deselect everything not in the selection we also have a couple other selection tools in the toolbar but they're slightly hidden any of the tools that have this little triangle in the bottom right of it means that there are some sub tools that we can access we get to those by left clicking and holding and then dragging our Mouse in selecting any one of these others so I'll drag over to The Tweak tool and then lift my mouse now with the tweak tool we can't do a box select dragging an empty space won't do anything but if I drag over an object then I'll move it around if I drag over the light then I'll probably get the size Gizmo but then if I left click and drag over it again then I can move it around let's left click and hold again this time let's go to the circle select and this one's more like a paint select lastly we have a lasso select again you can change the behavior for this in the tool properties but I usually like to use the Box select so I'll leave it at that one and set it back to its default settings and I think that's everything you need to know about selection for now we talked about a lot but the three main things that are most important to remember are that you can just left click to select objects shift left click to toggle selection remembering that there's both selected objects and the active object and that you can select all and none by going to the the select menu if you can do those three things then you're ready to move on to the next lesson where we're going to have some fun transforming [Music] objects
